Zac Efron completed rehab stay for cocaine addiction - report

It's been reported that actor
Zac Efron completed a stay in rehab this year and is doing well. Sources close to Efron tell
E! News that he checked in over alcohol and was now "healthy, happy and not drinking." However, a conflicting report says booze wasn't the problem Zac was dealing with, but rather cocaine was.

According to
TMZ, Efron developed a cocaine addiction, which became an issue while filming "Neighbors," with
Seth Rogen. Sources tell the site that Zac even missed some days during production, with one person adding, "It was common knowledge he was struggling with cocaine."

Sources also say that Efron experimented with Molly, a form of ecstasy. His reps haven't commented on the alleged drug use. Whatever issues Zac had seem to be under control, as he appeared in top form at the Toronto International Film Festival, where he was promoting his newest movie
"Parkland," which recounts the moments after the assassination of President
John F. Kennedy.
